First Alert Smoke Detector - Iris

How often does the Z-Wave smoke alarm from First Alert actually “wake up” to check for smoke? Can anyone confirm whether this device is in fact a “WakeUp Device” - RSS Role Type typically used for Z-Wave battery powered sensors OR is it a “FLiRS Device” - LSS Role Type typically used for battery powered door looks, window coverings, etc.?

I want to make sure these devices are safe and at the same time want to understand what my realistic expectations should be for battery life.

I read somewhere that the cheap z-wave smoke alarms from EverSpring and sold under a whole bunch of different brand names actually may be WakeUp type devices that allows for the auto-wakeup mode in their smoke alarms to be adjusted from ten minutes to max of one week with factory default setting of one hour. Not 100% sure whether or not this means what I think it does, but if so, YIKES!!! Does not seem safe or like that would be in line with Fire Code.

I believe the tradeoff for FLiRS devices is that since they are awake far more often, they have way less battery life. But more frequent check-in for smoke just sounds like it would be safer.

And speaking of battery life, how long is the typical battery life of the First Alert zsmoke and zcombo devices when used as part of the smartthings ecosystem?

Not sure if I can help, not sure what the specs are… but I’d be happy to do a lit-match test for you. I’m pretty sure the device will push notify straight away.

I think you’re confusing z-wave “wake up” versus detecting smoke/CO. When there is no smoke, the alarm will wake up the z-wave radio every so often to “check in” with the hub. My First Alert detector seems to check in about once per hour and report battery level.

However, the instant smoke / CO is detected it sounds the alarm, wakes up the z-wave radio and reports in.

Is it a First Alert with Z-Wave? I have a mix. The Z-Wave Fist Alerts work fine the non Z-Wave First Alerts, not so much.

This has probably already been asked, but I can’t seem to find a definitive answer… so, here goes…

I live in a 2 story house that has 7 hard wired smoke/co detectors installed. They are not smart devices. When one goes off, they all go off…

What I want… for them to be connected to my hub! well duh!!!

Ok, I want to buy one (1) smart detector, non-battery operated, and wire it into the existing system.

Here come the questions:

  1. If any of the dumb detectors alarm, will the smart one alarm?
  2. Will the smart one tell the dumb ones to alarm if it goes off?
  3. Or should I just reconfigure a contact sensor or something along that lines inline with one of the dumb detectors to trigger if there is an alarm anywhere in the house? I believe this could be done with a battery operated door/window sensor hard wired to the communication wire. Basically a work around instead of having to replace 7 alarms at 50 bucks a pop.

*** about #3*** No, the sensor would not be set up to trigger anything. It also would not affect the communication of the devices among themselves. And yes, I know how to do it properly when it comes to hacking the electronics… I was in the Navy… I have an awesome set of tools (what movie???).

Please give me your input, feedback, remarks, or whatever… I’m open to all of it.

oh yeah… and please… recommend a device for me… thanks.

Brand and model on the current hard wired nonnetworked ones?

BTW, if what you are looking for is primarily away from home notification, kidde has a really interesting solution which is a plug in networked device that just listens for the other alarms to go off and that is capable of sending notification. It’s intended for a retrofit situation. Gets decent reviews.

It’s not a smoke alarm itself, it will not trigger the other smoke alarms, but it gives you a notification capability for your existing alarms, which is often the main update people are looking for.

In the US, by code, smoke alarms have a very specific acoustic pattern, which is why this works. I just don’t know if it’s the same pattern in UK. It runs on Wi-Fi.

Because it can send multiple text notifications, you can use IFTTT for indirect integration with smartThings now in the U.S., and once that is fixed for the UK.

I like this one for a lot of retrofit situations, and if you’ve read my other posts you know that fire safety is a big deal for me. This is just a nice clean approach. There is one thing to watch out for, which is like a lot of Wi-Fi devices, it really works a lot better when it is not connected through a wifi extender, but that’s something you can test with him and see if placement makes a difference.

So that’s just one option. Literally plug and play.

As for your relay idea, sure, several people have done that. Usually with a relay and a door sensor. The issue with that is you have to match it based on model. And you’re paying for two devices anyway. So the plug-in ends up costing about the same, and should work any sensor that meets the US code.

You can search the forums, there are multiple topics on using the relays. Here’s a good one. I’d add any additional questions about the relay method to that topic.

Thanks. I’ve been reading the link and going from there. Lots of good information. I’m still working out this forum. I use my phone on here 98% of the time and it has done key features missing… Or I just haven’t figured it out yet.

But I digress…

I have a combination of co/smoke detector and just smoke detectors. The combo ones are in common areas; the hall upstairs, hall downstairs, and garage. The basics are in living and sleeping areas.

All of them are first alert hard wired detectors.

This thread is about the Z-Wave smoke alarm. You should start a different thread or search for others’ work on wired smoke alarms such as Monoprice door/window sensor and Smoke Alarm Device Type


If you would have read my first post you would see that I was asking questions that relevant to the thread. My second post was in response to another thread.

Starting another thread, in this already completely unorganized forum, on a topic that is already covered among hundreds of posts is asinine. Searches are unlikely to result in relevant information without complete frustration on the part of your users.

But if starting another thread will ease your mind and ensure you are able to continue your work, on things like making a stable app, then I will spend the rest of my day creating a plethora of threads.

Thank you.

I would like to note that your company has had a new hub, new equipment, new software, and a whole new user experience on the street for about a month.

A user getting updated information from fellow users that are both more experienced in the field as well other areas, plus the fact that many minds are better than a single mind on any subject, gives me ask of the reason in the world to continue my queries within this thread. It would probably be beneficial for the community if like missed threads wee combined into group threads, or rooms. Especially if those rooms were things like, contact sensors, alarms, motion sensors, etc…

New user to ST.

I just got one First Alert Smoke Detector and Carbon Monoxide Alarm!/products/smoke-detector-and-carbon-monoxide-alarm

Without reading the entire thread would someone mind telling me if i’m supposed to see both Smoke & CO in the app?

Thank you.

That’s all that I see as well.

Same here. I have one of the CO/Smoke and one Smoke only. They both appear the same in the mobile app.

Both smoke and carbon monoxide alarms use the same tile so that you can see the status from the devices list. The “Clear” will change to “SMOKE” or “MONOXIDE” and turn red when the alarm goes off. You can push the test button on the device and check that the tile changes to “TEST” to verify communication.

@duncan… Looks like the test button is gone…there was a test button in the app too. Right?

No, you’re probably thinking of the Z-Wave Siren device type. This is a sleepy sensor, so there’s no way to send a command to it.

Yeap. I stand corrected.

How do you send an email alert?

From the Smart Home Monitor page pick setup then work thru the smoke options.

What has changed with this device or Smart Home Monitor with v2? System used to trigger a full alarm when tested on v1, this was great to ensure everything worked as you want it to on an alarm (lights and notifications). Now when test is pressed on the device it only shows test on the device page and does not trigger any assigned lights or notifications.

The only way to ensure notifications, lights and door locks are triggered is to create an actual smoke situation, is this safe? Add the Test status back to the trigger, it was identified as a test in the notifications, so it was perfect, why the change?

@jimmay3 That’s lame that the behavior has changed. As an alternative you could try this:

I use it to test my smoke detectors.
